saline-casting machines such as those known ati @commercially under the trade mark Linotype 7 and particularly to those machines which are provided with circulating matrises each of which has two formative cavities,'one above the other. In these machines,

when it is desired. to compose what is known as a mixed line, that is to say, a line composed of letters of both the upper and lower formative cavities, the matrices of a co1nposed line must be supported in the first elevator' at two different levels so as to present the respective upper and lower forma tive cavities all in the same casting line. rljhis result has heretofore been attained by means of a rail or ledge movable into and yout of the channel of the first elevator, this` ledge being projected into the said channel .for supporting the matrices inthe upper poeition therein during the casting operation, and withdrawn therefrom to allow those matrices to descend to the common level preparatory to distribution. ln consequence the ledge being movable, and therebyc'ausin g wear between the relatively movable surfaces, it cannot' be relied upon, as it should be, to secure true alinement of the formative cavities. Attempts have already been madeto obviate this difficulty by providing a fixed rail or ledge in the first elevator, and, before distribution, bringing the matrices to their common lower level by a curved or in- @lined guide or cani against which they are caused to actwhen being moved out of the first elevator. This, however, has resulted in the rapid wearing of the matrices, as the guide was very short,r and the curve or incline thereof very abrupt.

According to the present invention the :first elevator, besides being provided with a fixed rail or ledge as heretofore., is also provided with means which enable the feet of all the matrices to be brought to a common level before the said matrices are pushed out ofthe first elevator. v ln the accompanying drawings, which two constrnetional forms of the im.-

proved mechanism, Figure 1 is a fore-and,

aft section through the head of the first elevator with the matrices still in the casting position, therein, and the said lirst elevator just approaching its highest position; Fig. 2 is a view similar to Fig. l but showing the first elevator vwith the matrices released and free to descend to--the common level; Fig. 3 is a view also similar to Fig. l. but showing the rst elevator in its highest position; Fig. 4; is a plan of the first elevator, and Fig. A5 is part of a front view thereof; Figs. 6 and 7 are diagrammatic 'views showing 'the means for widening the channel of the first elevator; and Figs. 8, 9, 10 and l1 are views respectively corresponding to Figs. 4, 5, 6 and "i of a second constructional form of the devices.

The first elevator head consists of two walls l and 2, of which the latter is guided in the former by a bar 3 whose forward end is provided with a double cam 4l., as shown best in Figs. 6 and .7, which. projects to the front of the part l. 'lwo tension springs 'normally hold the two parts of the first elevator head together. The known ledge 6 arranged on the part l, which serves to support the matrices in the lower position, is, as distinguished from other arrangements, movable horizontally in a. fore-andaft direction. lt isgnided in the part l and pressed by springs 7 (only one of which is shown) toward the rear of the first elevator. llhe springs 7 each encircle a rod 8 'provided with a nut or head 9 which limits the action of the respective spring. The ledge 10, on which the matrices stand when assembled in the app-er position, is xed. A cam or ,projection ll is fixed on the frame of the machine, in position to engage with the before described cam 4L when the first elevator is approaching its uppermost position.

The operation of the first elevator is as follows: After the line has been composed and a type-bar cast therefrom in the known way, the lirst elevator is moved to its uppermost position preparatory to distribution of the matrices. During this upward movement of the first elevator the cam 4 cornes into contact with the fixed cam 11l and is thereby pressed rearward as in Fig. '.7, sothat the channel of the first elevator head is widened and, at the same time, by the pressure of the springs 7, the ledge 6 is similarly pushedrearward as in Fig. 2. TheY matrices which roo lio Y were composed in the higher position thereby lose their support and fall by gravity into the position shown in dotted lines in Figs. 1 and 2. On the further upward movement of the casting slide the cam 4 passes the stationary cam 11, the part 2 of the first elevator, under the tension of the springs 5, returns to its forward position, and the matrices all being now at a common level as in Fig. 3, can be pushed on tothe toothed` rail of the second elevator which raises them to the distributer. The known depressor rail 12, which presses on the upper part of the matrices, can'also be used.

The arrangement shown in Figs. 8 to 11 corresponds generally to the before described arrangement, but instead of the tension springs 5 for drawing the t-wo parts 1, 2a of the first elevator toward each other, compressionsprings 13 are provided which constantly tend to push the two parts 1, 2a farther fromeach other. 'Ihe rear -part 2a of the first elevator has which slides along a rail 15 which` is provided with a notch or. cam 16. At the right moment the projection 14 enters the notch 16, as shown in Fig. 11, and the part 2 will, in consequence thereof, be pushed rearward by the springs 13 to allow the higher-` matrices to descend to 'the level of the lower ones.

The ledge 6 being movable as aforesaid, in the first elevator,.will be in its rearmost position so long as no matrices are in the said first elevator, and the entering matrices must push it forward into the positions shown in Figs. 1 and 3. In order the better to secure this'result, the end of the ledge with which the matrices first come into contact is rounded asshown at 17 in Fig. 4 and at 17a in Fig. 8, so as, at that part, to form a cam.

Having thus described my invention, I declare that what I claim and desire-to secure by Letters Patent is:- t

. 1. In a typographical line-casting machine, a first elevator having in combination front and rear walls forming between them` a matrix-receiving channel, and means c ona projection 14,

necting the two said walls together so that one wall canbe moved toward and away from the other wall.l

2. In a typographical line-casting ma` chine the combination with a first elevator having relatively movable front and rear walls forming between them a matrix-reeiving channel, springs imparting this relative movement 1n one direction, and cam devices operative to impart the said relative movement in the other direction during the travel of the irst'elevator to the distributing position.

3. In a typographical line-casting Inachine the combination with a first elevator having relatively movable front and rear walls forming between them a matrix-receiving channel, springs imparting this relative movement in one direction, a cam fast to one of the walls, and a stationary cam in the path pursued by the first named cam' when moving to the distributing position to impart the said relative movement in the other direction.

4. In a typographical line-casting machine the combination with a first elevator havingrelatively movable front and rear parts forming between them a matrix-receiving channel, a ledge for the matrices on one of the parts, movable relatively to that part to project more or less into the channel, springs moving the said ledge in one direction, and a cam on the ledge in the path of the matrices to move it inthe other direction.

5. v In a typographical composing machine, thel first elevator formed with its opposite walls relatively movable.

6. In atypographical composing machine, the first elevator formed with its opposite walls relatively movable, combined with -means to move the said walls toward and from each other. p

In witness whereof I have hereunto set my hand in the presence of two witnesses.
